  "prompt": "Genre: Mandopop / R&B / Gufeng; BPM: 119; Key: Am; Rhythm: Modern R&B groove with a steady kick/snare backbeat and driving 16th-note hi-hats.; Instruments: Programmed drums (punchy kick, layered snare), deep sub-bass synth, warm e-piano chords, breathy dizi-style synth lead, wide cinematic string pads in chorus.; Vocals: Male tenor, smooth and breathy timbre with R&B-style phrasing. Lead vocal is upfront, compressed, with lush reverb. Layered harmonies and ad-libs in the chorus.; Mood: Walking through a neon-lit city street in the rain after midnight, reflections blurring on the wet pavement.; Production: Polished, high-fidelity mix. Vocals are centered and clear. Wide stereo image with a deep, controlled low-end.; Language: Mandarin; Highlight: The downbeat of the first chorus, where sub-bass and wide strings enter, transforming the intimate verse into a widescreen emotional flood.",

  "cover_prompt": "生成一张极简主义的几何光影艺术图片作为无字音乐专辑封面。画面的核心是：一根燃尽大半的蜡烛侧面极简剪影，烛芯顶端结着一朵微微发光的灯芯花，烛身轮廓边缘被重度柔焦处理成模糊的光晕，整体沉浸在从深炭灰到暗琥珀色的水彩渐变背景中，四周保留大量呼吸空间，仿佛一张被烛光微微熏黄的旧宣纸在暗处静置。画面必须展现出微妙的高级材质肌理，特别是类似水彩晕染（Watercolor texture）或粗糙艺术纸张的触感。整体构图极度克制、留白（Minimalistic composition），注重光与影的柔和交错（Light and shadow interplay）。强烈要求：画面必须保持极致的安宁与静谧（Calm and serene），除了基础的、柔焦的简单几何图形（如模糊的圆、半透明的方块或柔和的线条）外，绝对不要出现任何复杂的现实物体、风景或人物！画面必须是无字封面，绝对不要生成任何文字、拼音或英文字母！绝对不要生成人物轮廓。传达出一种充满诗意、呼吸感与冥想空间的视觉感受。",
